Biography
My research is in algebraic and differential geometry and, recently, in number theory. In particular, I have been concerned with the Hermite problem (which asks for generalizations of continued fractions). I was an undergraduate at the University of Texas at Austin, a graduate student at Brown and an Evans Instructor at Rice before coming to Williams in 1989. I spent the academic year of 1992-93 on sabbatical at the University of Washington, the academic year of 2000-01 and also the year of 2012-2013at the University of Michigan, Ann Arbor and the academic year of 2016-2017 at the Insitut de Recherche en Informatique Fondamentale at what is now Université de Paris.
